Dry Sump Tank DLM 4 Gal. With Filter

The Peterson Fluid Dry Sump Tank DLM 4 Gal. With Filter is an essential component for high-performance engine builds where traditional wet sump lubrication falls short. Designed for serious engine builders, road racers, and track enthusiasts, this dry sump tank isolates oil storage from the engine bay, eliminating oil surge during hard acceleration and cornering.

This 4-gallon capacity tank features an integrated filter assembly that removes contaminants before oil returns to the engine, protecting bearing surfaces and extending component life. The compact footprint (15.25 × 14.75 × 25.1 inches) allows flexible mounting in tight engine compartments, while the weight of 14.3 lbs keeps underhood mass minimal—crucial for weight-sensitive builds.

Ideal for supercharged engines, turbocharged platforms, and high-revving small-blocks, this tank pairs seamlessly with aftermarket oiling systems on both carbureted and fuel-injected engines. The integrated filter element reduces maintenance downtime by consolidating scavenging and return filtration in one compact unit, making it a reliable choice for high-performance applications.
